SPL vs IMP

DDQ8-2 SPLvsIMP
Notice：This is a near-field curve(10cm with a magnitude offset post-processing). The measurement environment is a big sealed MDF box(volume is about 400L, 60cm*122cm*55cm, very similar to a infinite baffle). This is an authentic raw data without any smooth processing! Please give extra attention to the performance below 100Hz!

DDQ8-2 vs 8-inch TRADITIONAL WOOFER

DDQ8-2 VS 8-INCH

Notice: DDQ8-2'curve was tinted red & 8-inch woofer's curve was tinted blue, the two bottom curves tinted with light colors were their impedance comparision. DDQ8-2 has lower F0 and totally different bass performance! (click for large view)

Fig 2. 8-inch Woofer SPL(94dB) vs. THD (SoundCheckTM)

Notice: DDQ8-2's THD is much lower than traditional structure 8-inch woofer. At Fs the DDQ8-2's THD is only 1.6% but the comparison is 6.4%. At 10Hz the DDQ8-2's THD is 17.5% but the comparison is 31.8%. So DDQ could give a much better bass quality!(click for large view)
